Essays on Bacteria

Did you know, bacteria are a living and thriving species? “There are over ten million different types of bacteria! They can live within soil, in the ocean, or inside the human gut”. I am very interested in seeing what type of cleanser best kills these...

New research is spurring exciting developments showing the presence of trillions of bacteria that survive inside our body and how those bacteria affects our genes. Science is driving us all nuts with such mind blowing yet fascinating information regarding new developments. We have always known...

Early observations by application of specific strains revealed that virulent pneumococci were surrounded by a structure now recognized as the capsule. The capsule played a central role in the discovery of the ‘transforming principle’ since it was using this genetic trait and this microorganism where...

Introduction Recent studies have allowed us to come to the conclusion that we are super organisms in which microbial symbionts play essential physiological functions. The human microbiome has emerged as the crucial moderator in interactions between food and our body and can change our mind...

“ In 1978, genetically engineered human insulin was produced by utilizing a new technology that would hopefully produce unlimited amount of human insulin by controlling the power of tiny microorganisms. People had used bacteria to enhance their lives from a long time ago. For instance,...

A microorganism is a living organism and they can only be seen through a microscope. Bacteria Bacteria cells are prokaryotic cells (single celled organisms). Bacteria cells have a variety of different organelles including a single circular strand of DNA, plasmids (small rings of DNA), a...

In 2017, the World Health Organization compiled a list of “priority pathogens”, this list included 12 antibiotic-resistant bacteria. Acinetobacter baumannii made the slot for “priority one pathogen for antibiotic research and development. ” A. baumannii infects patients in critical care units, demonstrates multi-drug-resistance and can...

A facultative aerobe is an organism that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen is absent. An obligate aerobe, by contrast, cannot make ATP in the absence of oxygen, and obligate...

In this review, we mainly focus on persistence colonization of Helicobacter pylori in the human gut. In recent times we have come across some novel strategies used by this bacterium can be a cause of prolonged existence in human or evolution with another bacterium to...

Poverty is one of the world’s recurring and concerning issues which has affected countries, especially third-world countries, and this includes Philippines. During the first half of 2014, 25.8% of the Philippine population suffers from poverty, which decreased to 21.6% in 2015, and was then increased...

Bacterial biofilms now represent the dominant bacterial growth lifestyle in different habitats including natural and clinical environments. Bacterial cells switch between the free-living planktonic mode and the biofilm growth mode, through multiple mechanisms that include adhesion to a substratum, increasing their aggregation into microcolonies and...

“ Bad breath is caused by odor-producing bacteria that grow in the mouth. When you don’t brush and floss regularly, bacteria accumulate on the bits of food left in your mouth and between your teeth. The sulfur compounds released by these bacteria make your breath...

Production of crude alkaline protease from Bacillus cereus strain S8 (MTCC NO 11901) was carried out by statistically optimized media supplemented with molasses, 1% (w/v); potassium nitrate, 0.75% (w/v); salt solution, 5% (v/v); {MgSO4.7H2O, 0.5% (w/v); KH2PO4, 0.5% (w/v)}; FeSO4.7H2O, 0.01% (w/v) and CaCO3, 0.5%...

The Paramecium tetraurelia is an unicellular ciliate that can be found in almost any sample of still water. Paramecium tetraurelia is a widely distributed, free-living unicellular organism that feeds on bacteria and can easily be cultured in the laboratory(Beisson,et al.,1970). Its large size and complex...

Extremophiles are organisms that live in conditions which humans consider “extreme.” “Extreme” environments include but are not limited to extreme pressure, extreme cold, intense heat, highly acidic environments, and highly saline environments. These conditions were once believed to not have the ability to sustain life....

Aim: The present study was undertaken to study the incidence of microbial spectra in gallstone disease and effect of bacteriobilia on wound infection. Introduction: Biliary calculus disease is commonest disorder affecting the gastrointestinal tract and remains the most commonly encountered cause of morbidity. There is...

Acidithiobacillus strains SP5/1 and HV2/2 are rod-shaped, Gram-negative, γ-proteobacterium, aerobically pyrite-oxidizing and Acidophilic bacteria that thrives optimally at 30°C and 45°C respectively (Klingl, Moissl-Eichinger et al. 2011). S-layer molecular structure similarity in symmetry in the closely related species can be used as a taxonomic characteristic...

Vibrio cholerae is found mainly in raw vegetation, water containing sewage and raw seafood. Stagnant water and certain types of food, including seafood, raw fruits and vegetables, and grains are the most common sources of cholera infection. When a person consumes contaminated food or water,...

Right through history, from the genus Mentha L. and the family (Lamiaceae), species which includes about 260 genera and more than 7000 species are being used worldwide and one example is Mentha piperita L. (Brahmi, Khodir, Mohamed & Pierre, 2017) commonly known as peppermint a...

The blue green algae are the primitive members of the plant kingdom. The most of the blue-greens algae are unicellular, photoautotrophs and aerobic. They require mainly light, inorganic matter and oxygen for their growth. Spirulina are filamentous blue-green algae (cyanobacteria) always attracted the interest of...

Cyanobacteria are photosynthetic bacteria that share some properties with algae and are found naturally in lakes, streams, ponds, and other surface waters. Cyanobacteria can rapidly multiply in surface water and cause “blooms.” Several types of cyanobacteria, for example Anabaena sp have gas-filled cavities that allow...

Introduction Diagnosis of fowl cholera depends on identification of the causative bacterium, P. multocida, following isolation from birds with signs and lesions consistent with this disease. Presumptive diagnosis may be based on the observance of typical signs and lesions and/or on the microscopic demonstration of...

I read the article “A stealthy superbug appears to be spreading in us hospitals, study finds.” And for the article on an additional case study, I read “With latest Zika research, our picture of the virus gets cloudier.” Just as mysterious as other viruses, scientists...

Antibiotic resistance crisis is happening now and it seems like there is no solution to it yet. Everyone knows that the antibiotic resistance is elevating to dangerously high levels in all parts of the world. The antibiotics that were used to save millions of lives...

Results Isolation of sponge-associated bacteria from 3 different sponges resulted 80 bacterial isolates which are morphologically different. Nine bacterial isolates were obtained from sponge Hyrtios sp., 20 bacteria isolated from Smenospongia sp., and 51 bacteria isolated from Verungola sp. Sponge-associated bacteria with anti-Vibrio spp properties...
